So now.. how do we do this for framebuffers?
My memory is suspect, but first you would need to make sure all of
VRAM is mapped. Then there is a value in fb that says how much of the
VRAM it is using. Anything above the max is fair game if X isn't
running. Note that the amount of VRAM in us
a bit more relaxed.
These drivers are going to get hit with immediate patches. The DMA is
not broken out so that AC97 support can be fixed for the Efika.
I haven't touched these up for the driver that was just posted.

All this patch seems to be doing is removing class I2C_CLASS_HWMON via
a device tree flag, PROBE.
Why do you need to do this? The OF conversion patch that is working
its way through the system lets you put the address of the device into
the device tree node. Probing shouldn't be necessary

A fourth scheme is to do it at compile time. But that means no
universal firmware images that support multiple hardware revisions. We
have this one today too.

I experimented with this on my own trees.
2xx_PSC_SICR_CELLSLAVE and MPC52xx_PSC_SICR_GENCLK when the
fsl5200-cellslave attribute is present.
We need to tie the two PSCs up like this to get the audio clock in via
PSC1 and then have PSC2 generate the frame clock when the i2s data is
transmitted.

In order to reduce options, can the psc-i2s driver always try to use
mpc5200 clocking, then let the codec or fabric driver override it?

Has anyone tried writing a RedBoot type partition table onto their
flash device? If it is there the kernel will read the partition info
from it. It's a config option in the kernel flash support section. Is
there a utility for creating these tables?

into a bunch of different pieces but the contents of this patch are
essentially unchanged.
I don't care which tree it uses to get to mainline, I'd just like to
see it get merged.

As part of this module's initialization it may need to request_module
generic mmc core module, but I haven't traced things out that far yet.
None of these parts should need to be compiled in, they should all be
capable of being loaded as a modules.

Convert i2c-mpc to an of_platform driver. Utilize the code in drivers/of-i2c.c
to make i2c modules dynamically loadable by the device tree.

arch/powerpc/sysdev/fsl_soc.c | 122 -
drivers/i2c/buss
Add the of_find_i2c_device_by_node function. This allows you to follow a
reference in the device to an i2c device node and then locate the linux device
instantiated by the device tree. Example use, an i2s codec controlled by i2c.

This version adds of_find_i2c_device_by_node() which is needed by ASOC drivers.
To make it work I had to make the i2c bus struct visible. It also picks up a
couple of other minor fixes that have been posted to the lists.

Convert i2c-mpc from a platform driver into an of_platform driver.
This patch is much smaller since Jochen already added
of_find_i2c_driver(). Versions of this have been posted before.

Something that went into 2.6.26 has broken the image build for the
Efika. Matt has confirm it too.

I'm staring at a baseboard for the pcm030 in my hand, I don't see any
AC97 hardware. It has two serial, two CAN, ethernet and power. Where's
the AC97?
